Windows 7: Windows 7: Readyboost

ceroberts75, I have found that some SD cards and USB flash drives don't work with readyboost. I have 3 SD cards and only 2 works as readyboost drives. So if the memory your using isn't fast enough it won't work. Even my new WD USB HDD is seen by 7 as a possible readyboost drive but when I goto the settings tab it won't take.

I know this is an old thread, but something was bugging me. After deciding to install Windows 7 to replace XP on all the computers in my house, some of which are older, I decided to find out more info on the advantages of ReadyBoost for the older systems. I'm all well and good with the concept, and the roughly $40 needed to buy 4 USB thumb drives for the 4 systems that need it, seems well worth it. But as I was doing research, I was shocked to find that Windows 7 supports up to 8 devices containing up to 256GB.

Does anyone have any idea what the thinking behind this was? Why would anyone need 8 devices? Why would anyone need or want to spend $500+ on 256GB of USB flash? Why would this even be engineered to handle such a configuration? Could any system even utilize such a configuration?

Just curious, but I've been scratching my head since I read about it, and wondered if anyone had any clue.

Slap in your flash drive. Open "my computer", right click on the flash drive and the readyboost tab is there.
I recommend you don't use all the space on the stick, keep a bit empty otherwise it shows up as 99% fragged

What happens if the flash drive is missing when you boot your computer. I tried something foolish in hindsight. I made a ram disk a readyboost drive. Of course, the ram disk will not be there at boot, it will only be ther after the OS has started up and is probably close to finishing loading. The next time I rebooted my machine, I can't even get it to POST. Nothing gets to the screen. I had no problems before this.

I am just getting Phoenix BIOS POST beeps 1-3-3-1. I get the beeps instantly when I turn on the power. I think that this is a memory error, but Tyan web site won't give me access to the manual. Could POST be looking for the memory I dedicated to readyboost on my ramdrive? Or is readyboost memory only used when the OS starts to load. This thing is stopping long before the OS starts to load.

I know nothing about Tyan, but it seems very strange that they won't allow you to download the manual. What BIOS does your motherboard use? BIOS beep codes are usually standardized by the BIOS brand, and can be Googled. You need more than the sequence that you posted, because the codes are usually composed of long and short beeps, so you need to listen more closely.

I have a Tyan S5397 motherboard. The manuals are on the Tyan site, but the site is screwed up and for some reason, when I click on the get manual link, I get a page saying "Website Declined to Show This Page". I get this message for any of the tyan support documents.

I have Phoenix BIOS and all the beeps seem to be the same length, but they come in groups. 1 Beep, a pause, 3 beeps in quick order, a pause, 3 beeps in quick order, a pause, 1 beep. Occasionally, the sequence will begin again after about 1 to 2 minutes. There is an LED on the motherboard with the code E4 on it.

I havent been able to find a manual in a google search, but i did find a reference to a 1-3-3-1 beep code for Phoenix BIOS on a different machine. They said that the code means that your memory is in the wrong slot for a single dimm configuration. I have 4-4gig DIMMs spread across the available 16 slots as per the manual's recommendation (the manual that I now cannot find). That configuration has been working well for about a year.

I'm just thinking out loud, with no real conclusion, but while itseems obvious that there is a memory issue, I doubt that it is either ReadyBoost or the RAM disk causing the problem, because as you said, they don't exist during the BIOS run. I have no idea of what that E4 code is about, but it would be helpful to know, if you can Google that. As it stands, if the problem is one of memory, it would seem that either you have a RAM disk that went south, or dust or corrosion had built to the point of effecting the system. Even though it was working properly prior to your last reboot, it may just be a coincidence of timing. I would remove, inspect and reinstall the RAM, then run Memtest 86, letting it run a number of passes to see what it says.

Thanks for the response, I was wondering if Readyboost somehow gets the memory controler to map memory to the disk that it thinks is available, and now that that disk is not available at boot, I am getting memory erors. I don't know if readyboost works at this low a level.

A google of E4 and Tyan did not produce anything helpfull. I have the memory watercooled, so removing it is a REAL hassle. I regret ever watercooling them, it makes the case cramped, and working on the memory a real pain. I don't think that I gained much by it either, I still ended up putting a fan in the center of the case. But I think that you are right, that should be my next step.

Windows ReadyBoosthi,
my pc has 3GB DDR2 RAM, but i can only use 1,8 GB because 1,2 GB are shared with my PNY GTS 450.
if I enable windows readyboost with an 8GB USB key, will i get a performance improvement?

Any reason to use Readyboost on Windows 7 X64 with 8GB?Ive been reading about how windows 7 is supposed to improve and remove the restrictions of the readyboost that was in windows.
My question is if its even worth it on an X64 system with 8GB DDR3 RAM?
Would it improve the system speed even more having stuff cached right on the usb?
I have a...
